FFT Root Raised Cosine Filter

This block creates a finite impulse response (FIR)-based root raised cosine filter implemented using the FFT. For filters with more than a dozen or so taps, implementation with the FFT is much faster than with straight convolution or a polyphase implementation.

This block is a convenience wrapper that combines a GUI with the FFT Filter block and the firdes.root_raised_cosine taps generating function.
